Penhale, from Birmingham, is the captain of the 31st Alabama Infantry and said he's been re-enacting for almost eight years. However, today he and Lieutenant Pete Smith from Lineville are portraying the 1st Alabama artillery.

"At the time of the siege the artillery units were trained in artillery and infantry. Today we are acting as men cross trained," Penhale said.

"We try and do as much with the naval battle and infantry and artillery in one weekend and we get as accurate as possible," he added.

Smith said he participates in re-enacting because he enjoys history, getting outdoors and meeting new people.

He said the 31st Alabama Infantry, made up of 10 to 15 people, were re-enactors at Gettysburg last year, and will be in Atlanta next month. But next time, they'll be wearing blue suits.
